AaronST185 Regular Location: West Hobart Registered: December 2004	Re: Overboosting ST185 Thu, 13 January 2005 02:47 This is a summary of the back pressure thing that was posted on www.gt4oc.net Quote: Couple of things, it's not that the wastegate is too small to flow the required gas to stop boost creep - it flowed enough before changing exhausts - it's that you've made is so much easier to flow through the turbo than through the wastegate, by reducing back pressure, similar to how a FCD works by changing a resistor value to bleed off more voltage in one path than another Because of that, there's a few things you can do - increase back pressure as people have already suggested, but you can also increase the flow of the wastegate by porting so that more air can exit via that route again - depending upon your amount of boost creep though, that may or may not be enough on it's own - going external wastegate is the same principle [Report message to a moderator]
